An acoustic beam simulation makes use of ultrasonic beams that are used in a phased array (PA) ultrasonic, which is considered to be an advanced method of ultrasonic testing.This method is better at finding flaws in manufactured materials such as welds. The acoustic beam simulation mimics how the ultrasonic beam in a PA probe can be focused and...

Copper Strip Corrosion

Definition - What does Copper Strip Corrosion mean?

This is a qualitative method that is used to determine the level of corrosion of petroleum products. In this test, a polished copper strip is suspended in the product and its effect observed.

The method is well suited for specification settings, internal quality control tools and development and research on aromatic industrial hydrocarbons. It also detects the presence of harmful corrosive substances, like acidic or sulfur compounds, which may corrode the equipment. The value of this test is reported in SI units.

Copper strip corrosion is also known as the copper strip test.

Corrosionpedia explains Copper Strip Corrosion

This test can be used for testing gasoline, solvents, natural gasoline, kerosene, diesel fuel, distilled fuel oil and lubricating oil, among other products, using test baths. At elevated temperatures, a copper strip that has been polished is immersed in a sample, usually 30 ml. The strip is then removed and tested for corrosion and a classification number is given. The number ranges from 1 to 4 after a comparison with the ASTM copper strip corrosion standard is done.

There are several methods and tests available. One is the test bomb bath, 7151K59. In this test a thermostatically controlled water bath is used to immerse copper strip corrosion test bombs. This must be done at the right depth as per the ASTM requirements. This test has several specifications that are identified with it:
